We report an effective therapeutic approach of mechanical circulatory support for a patient with cardiogenic shock and respiratory insufficiency due to fulminant myocarditis. An Impella 5.0 was utilized as a left ventricular assist device (VAD) and percutaneous veno-pulmonary extracorporeal membrane oxygenation (ECMO) as a right VAD. These devices were implanted without sternotomy or thoracotomy. Although a combination of Impella and veno-arterial ECMO has been reported as percutaneous biventricular support, there are concerns that this combination is not beneficial for myocardial recovery in patients with respiratory insufficiency, because Impella expels insufficiently oxygenated blood from the left ventricle to the coronary arteries. Our approach took advantage of percutaneous implantation of ECMO and temporary VAD, eliminating the drawbacks of both devices, thus providing a more effective and less invasive form of temporary biventricular support.
我们报告了一种机械循环支持的有效治疗方法,用于治疗因暴发性心肌炎导致心源性休克和呼吸功能不全的患者。使用 Impella 5.0 作为左心室辅助装置(VAD),并经皮置入静脉-肺动脉体外膜肺氧合(ECMO)作为右 VAD。这些设备无需开胸或开胸即可植入。尽管已经有报道称 Impella 和 veno-arterial ECMO 的联合应用可作为经皮双心室支持,但有人担心这种联合应用对呼吸功能不全患者的心肌恢复没有益处,因为 Impella 将含氧不足的血液从左心室排出到冠状动脉。我们的方法利用了 ECMO 和临时 VAD 的经皮植入,消除了这两种设备的缺点,从而提供了一种更有效和微创的临时双心室支持形式。
